Inventor: RENAUT YVES
IPC: A22C29/04
Filed: 1996-01-26
Abstract: A process and device for preparing bivalves, in particular oysters, for opening. The process consists of partially opening the bivalve, then encircling the adductor muscle of the bivalve with a ring or similar, one part of which, designed for gripping, remains outside the bivalve, so that, when the bivalve is subsequently closed, the adductor muscle can be severed by pulling on the aforesaid gripping element. The device comprises a wire (1) shaped as a loop (12) to which a gripping element (2) is linked, to be inserted into the loop (12) after the latter has been placed around the adductor muscle (3) of the bivalve.

Title: Polyolefines are prepared by vapour phase - pyrolysis of an aldehyde halo ether addition
IPC: C07C29/10
Filed: 1970-01-26
Abstract: Polyolefins are prepared by vapour phase pyrolysis of an aldehyde haloether addition product using a molecular sieve. Pyrolysis of the addition product of olefin (I)/haloether (II) in the vapour phase in the presence of a molecular sieve gives the polyolefin (isoprene), a haloacid and an alcohol. (II) (chloromethyl methyl ether) is prepared by reaction of a haloacid, an alcohol and an aldehyde. (I) may be isobutylene. (I) and (II) are produced at the hourly wt. rate of 0.1 to 10. Pressure during pyrolysis is 0.1-10 atm. and temp. is 75-500 degrees C. The process gives improved yield and makes recovery of the polyolefin easier. The haloacid and alcohol can be recycled to form (II).

Title: Dry hot compressed air for blast furnace - produced using heat exchanger and dehydrator assembly upstream of hot air furnaces
IPC: C21B9/16
Filed: 1976-08-13
Abstract: The air passage between a blower and hot air furnaces for a blast furnace incorporates a dehydrater assembly having a gas permeable rotor impregnated with a regenerative hygroscopic substance and a cooler for condensing the moisture in the air. a heat exchanger is arranged in the passage so that some of the hot compressed air coming from the blower can transfer its heat to the dehydrated air coming from the dehydrated assembly. All the air to be introduced to the hot air furnaces is passed through the dehydrater assembly and the heat exchanger and is dehydrated. It is unnecessary to supply any external hot air to regenerate the rotor. The moisture content of the treated air can be reduced without any significant loss of temp. and pressure. Air leakage between the regenerating and dehydrating zones in the dehydrater is prevented by sealing clearances with packing elements and externally introducing dry pressurised air into the sealed spaces.

Filed: 1978-09-26
Abstract: Reaction of 3-phenoxytoluene with bromine at elevated temperature yields 3-phenoxybenzyl bromide, 3-phenoxybenzal bromide, or a mixture thereof. In contrast to teachings of the prior art, phosphorus halide catalysis or u.v. activation is not required to achieve a desirable amount of side-chain bromination with a minimum of nuclear halogenation. For example, it was observed that at 265+/-5 DEG  C., good yields of the desired benzyl and benzal bromide were obtained, but no nuclear halogenated by-product was detected by gas chromatography.
